Lesson Plan on Solving Addition and Subtraction Word Problems for First Graders

Lesson Title:Solving Addition and Subtraction Word Problems for First Graders

Lesson Objective: Students will be able to understand and solve addition and subtraction word problems using manipulatives, pictures, and mathematical symbols.

Materials:

  • Addition and subtraction word problem worksheets
  • Manipulatives (such as counters or base 10 blocks)
  • Picture cards related to the word problems
  • Chart paper
  • Markers

    • Introduction (5 minutes):

    1. Begin the lesson by reviewing the concepts of addition and subtraction using manipulatives.
    2. Write an example of an addition and subtraction word problem on the chart paper, such as “There are 5 apples in a basket and John takes away 2, how many apples are left in the basket?”
    3. Have the students use the manipulatives to solve the problem and model the solution using mathematical symbols.

    Direct Instruction (15 minutes):

    1. Pass out the addition and subtraction word problem worksheets to the students.
    2. Review the mathematical symbols for addition (+) and subtraction (-) and their meanings.
    3. Show the students the picture cards related to the word problems and have them explain what they see in the pictures.

    Guided Practice (20 minutes):

    1. Have the students work with their partners to read and solve the word problems on the worksheets using the manipulatives and pictures to help them visualize the problem.
    2. Circulate around the room to assist and check for understanding.
    3. Have the students explain their thinking and solutions to the class.

    Independent Practice (10 minutes):

    1. Have the students complete a few more word problems on their own using the manipulatives, pictures and mathematical symbols.
    2. Provide extra support and assistance as needed.

    Closure (5 minutes):

    1. Review the key concepts of addition and subtraction word problems.
    2. Have a few students share their solutions to a word problem.
    3. Remind the students that solving word problems is an important math skill and will be used in many areas of their lives.

    Assessment: Observe students during independent practice, check the worksheets and informally assess students’ understanding of the addition and subtraction word problems using verbal questions. Also, check if students are able to use the mathematical symbols correctly, use the manipulatives and pictures to solve the problems and explain their thinking.
